The Lowdown

Alright, let's get into it. The surf's been pretty flat and jumbled out here, but that's the game sometimes. We've got a bit of a wait on our hands before things start moving, so don't get your hopes up for the next couple of days.

The first real window where you'd want to be a bit more than just curious is Thursday morning, the 17th. We're looking at a clean 5ft of south swell wrapping in with a 10-second period. The wind's light offshore, a proper cross-off, and that's about as good as it gets for a Thursday. The water's sitting right where it should be for this time of year, so nothing weird there. The energy's kicking up to a modest 717, which is a solid step up from the junky stuff we're dealing with now. It's a decent start, but it's not the main event.

Honestly, after that, it fades a bit before things get interesting again. We have a few clean, small days, but nothing with any push. You'll get some fun ones early next week, but the swell is a touch on the short-period side, so keep your expectations in check.

The real standout, the one you circle on the calendar, is Friday the 25th. This is the pick of the whole run. The models are showing a solid 5ft of south swell pushing through with a 13-second period, and it's got that clean, lined-up look to it. The combined energy jumps right up to 995, which is the punchiest it gets in this whole forecast. With the light offshore flow that morning, that's a session for the high-performance board. This is a proper groundswell, the kind that the reefs and points will love, but at a beach, you might see it start to stand up and wall a bit more. It's a classic case of the better the period, the better the shape, but you gotta pick the right bank.

There's a little bit of a pulse building after that, with a couple more clean days to close out the month. The 30th has some potential with a 5ft SSW swell and a 12-second period, but the wind is a touch more on it, and the energy, while decent, isn't quite as strong as the 25th. It's a solid second-choice option, but it's that Friday that has the magic.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
